Carrier Grade Voip Enterprise

The importance of VoIP solutions in heightening productivity of SMEs (small and medium enterprises) cannot be over emphasized. The cost savings, specially in the long run are significant. The per-employee productivity is likewise higher – thanks to the mobility features of VoIP.

However, penetrating the SME VoIP market ofttimes comes with sure roadblocks and difficulties for VoIP service providers. VoIP service suppliers can not spend monetary resources to evaluate the networks and planned deployments of the client organizations. The circumstance is not that dissimilar post deployment as well. Call set up and call quality troubles need effective tackling and the need for an on-site technician arises. The importance of lifecycle management solutions may be understood in this context. With such solutions in place, VoIP service suppliers do not have to worry regarding quality of service.

For the discussion to go any further, we must have a lot of idea regarding ‘lifecycle management solutions.’ More often times than not, the VoIP service suppliers offer their services to little and medium enterprises. Maintaining carrier-grade service quality with hassle free deliverance of VoIP solutions over a assortment of networks is in general a problem. Scalability and ease of deployment are two major areas of concern for the service providers. Lifecycle management solutions, deployed within the organizational context of SMEs, take care of this specific need. These solutions play an essential part in monitoring and reporting elaborate stats on all the VoIP calls. The method of deployment is simple. Moreover, the fact that the solutions may be more and more scaled to take into account the altering market dynamics, also go in their favor.

VoIP solution suppliers are doing all that it takes to make the routine of integration a hassle free one – for them as well as for the endeavors making the much necessitated shift from established communication networks to VoIP telephony. A huge number of VoIP service suppliers are more and more depending on ‘lifecycle management solutions’ to heighten the scalability and ease of deployment of specialized VoIP services.

If you have any doubt whether VoIP is vulnerable . . .
By Stephen Northcutt
A quick read of the original 1/3 of the book will heal you of your doubts VoIP may be attacked forever! It was closely painful reading; exploit approach after exploit approach, but I mean that in a good way like the pain you feel in your muscles after exercise.

I was excessively affected emotionally when this book came out, I have been following galore of the author’s Thermos and Takanen work and I think they were the perfective team for this book.

I feel that Chapter 3 and 4, threats and attacks and VoIP vulnerabilities are by far the firmest chapters and they alone are worth the buy price of the book.

The majority of the rest of the book is focalized on mitigating controls and it is solid writing, solid research, but not rather at the level of the pen test side of the book.

Chapters 10 and 11 are worthful to any individual taking into account a VoIP deployment including a deployment where you are depending on a service provider. The charts and diagrams are clear and easy to understand, the whole book team is to be commended for that, this is a complex subject.

If you are even thinking in regards to VoIP, you must read this book.

Valuable VoIP Security Information
By Tony Bradley
There are a lot of gains to VoIP and IP-based communications. However, relying on your network infrastructure to transport your telephone communications renders your telecommunications vulnerable to almost all of the same issues and threats as your network. On top of that, there are also distinctive attack vectors introduced by VoIP. As organizations race to deploy VoIP and experience the benefits, most would in all probability gain from decelerating down to consider the security significances and create suitable controls to protect their communications.

In Security VoIP Networks: Threats, Vulnerabilities, and Countermeasures, writers Peter Thermos and Ari Takanen do a superb occupation of illustrating the insecurities of VoIP. Not to suggest that it is just so inherent insecure that it ought to never be used, but C-level execs, and IT managers and administrators must be intimate with the data in this book before moving forward to deploy VoIP.

Chapter 2, ‘VoIP Architecture and Protocols’, provides a solid foundation on the basic elements and technologies that make up VoIP. It is the next couple chapters that are the most priceless though. In ‘VoIP Vulnerabilities’, and ‘Threats and Attacks’, Thermos and Takanen demonstrate the weaknesses of VoIP and the simplicity with which VoIP communications may be disrupted or intercepted if not set up properly.

Chapters 5 – 8 make an analyzation of dissimilar security controls and shelter mechanisms. One issue I had was that it was difficult to draw a one-to-one correlation and find the security countermeasures to defend versus attacks identified earlier. The info is solid though.

The book wraps up by supplying a look at what a VoIP security framework ought to entail, and architecture diagrams to help you formulate and deploy a secure VoIP solution.

Good introduction to VoIP security
By B. Robert Helm
This book was utile for understanding VoIP security protocols, including more or less obscure ones such as SIP over TLS. The threats section looks like it will be valuable for convincing managers to take VoIP security seriously. I employed the book to valuate Microsoft’s new VoIP merchandise (I work for an analyst firm, Directions on Microsoft, that covers the company) and found it very helpful.

I wish that the book were coordinated to relate the threats and attacks to the countermeasures more distinctly — I find it requiring little effort to understand a security protocol when someone shows me what attacks it may and can’t block. I’d like to see a book like this that focuses on SIP/RTP VoIP in more depth and leaves out H.323 — I recognise H.323 is more widely deployed, but SIP/RTP seems to be where the big marketers are headed. Still, these are minor quibbles — I would commend this book to any person who needs an introduction to VoIP network security.
